DA0-002 Data Governance Practice Question
A data analyst is tasked with presenting the results of a customer churn analysis to a group of marketing managers. The model identified that customers with low engagement scores are 3 times more likely to churn. The analyst wants to effectively communicate this finding to persuade the managers to focus on engagement. Which of the following is the most compelling way to present this insight?
⚠ Common exam trap
The trap is choosing a visually appealing chart or detailed table over a business-impact metric, confusing technical presentation with persuasive communication.

Correct answer & explanation
✓
Calculate the potential revenue increase if engagement improves by 10%
To persuade marketing managers, the most compelling presentation is to quantify the business impact—calculating the potential revenue increase if engagement improves by 10% translates the churn insight into financial terms that resonate with managers. This directly ties the analysis to a business outcome, making it more persuasive than raw statistics or charts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Show a table with raw churn rates by engagement score
Why it's wrong here
A raw-rate table forces marketing managers to read and compare numbers themselves, burying the three-times relationship the analyst needs to persuade with. Tables suit detailed audit or reconciliation work, where exact figures per segment matter, but here the goal is a single comparative insight, not exhaustive data.
- ✗
Use a bar chart comparing churn rates of low vs. high engagement
Why it's wrong here
A bar chart comparing two engagement groups presents the comparison but does not convey the threefold risk magnitude or drive urgency. Bar charts suit categorical breakdowns across many segments. A risk-ratio or lift visualisation communicates the multiplier effect that persuades managers to prioritise engagement investment.
- ✗
Show a scatter plot of engagement score vs. churn
Why it's wrong here
A scatter plot of engagement against churn shows individual observations and correlation shape, not the three-times risk ratio between low and high engagement groups. It is tempting because scatter plots reveal relationships, and would be correct when exploring whether a continuous association exists before modelling.
- ✓
Calculate the potential revenue increase if engagement improves by 10%
Why this is correct
Quantifying the revenue uplift from a 10% engagement improvement translates the statistical finding into financial impact, which is the metric marketing managers are accountable for. This satisfies the stem's persuasion constraint by framing churn risk as potential gain, making the engagement investment decision concrete rather than abstract.
